The Passive House Builder is a company run by Dai Rees. Dai is an engineer, renewable energy specialist, electrician and qualified passive house designer and builder who lives in Herefordshire, on the welsh border. He has a passion for all things that help reduce energy consumption and reliance on fossil fuels.

TPHB has come into being after Dai constructed his own self-build passive house in 2016/17 and this has lead to further projects for clients. Dai works closely with architect Charles Grylls (Dempsey DeCourcy Architects) and Nick Grant (green guru at Elemental Solutions) as well as other designers and architects. We have a team of enthusiastic carpenters and builders who construct the timber frame houses and use trusted sub-contractors for other specialist works.
